Beschrijving
Hoffmann pinchcock 30 mm is a laboratory hose clamp designed for reliable compression of flexible tubing and controlled flow restriction. Fabricated from nickel-plated brass and fitted with a flap, it allows secure opening and closing of soft hoses up to the 30 mm size without threaded connectors. The robust metal construction ensures lasting performance during frequent adjustment in laboratory and technical settings. At a net weight of 0,024 kg the clamp stays manageable and easy to locate on the tubing run. It functions well as a pinchcock or hose clamp in chemistry, biology, teaching and general laboratory work for temporary or ongoing control of liquids or gases. This Hoffmann-style pinchcock from manufacturer Usbeck is supplied as a single piece and suits common laboratory tubing diameters for the 30 mm format. The nickel-plated brass body offers corrosion resistance under typical laboratory conditions, while the flap enables practical everyday operation. Appropriate for research benches, preparation areas and industrial laboratory processes needing simple, durable hose regulation.

Questions about Tubing Clamp Hoffmann 30 mm
What is this article?
Tubing Clamp Hoffmann 30 mm is the article on this page. Luminix Health distributes Usbeck for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labmateriaal.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
